Currently, the main scheme of offline multi-bin task management is as follows:
the method comprises the steps that an IDE integrated development environment is used for developing off-line data processing tasks (hereinafter referred to as tasks for short), the tasks are mainly divided into SQL-type tasks or script-type tasks so as to clean and logically process data, task codes are submitted to a code review center Gerrit, a task scheduling center pulls the latest tasks from the code review center Gerrit within a fixed time (generally 0:30 minutes in the morning), the task scheduling center calculates task dependency relations and submits the latest tasks to a data calculation cluster according to task scheduling time, and the tasks are operated in batches.
The current solution has the following problems:
(1) the current task scheduling center can only pull the latest task at a fixed time point, the current temporary data processing scene cannot be supported, the task is not released in time, and the process is not flexible;
(2) the current task scheduling center uses an open source scheduling system, which is not friendly to developers and has high cost, and task management operations such as task scheduling setting, task offline, execution, number compensation and the like are completely dependent on developers, so that the developers cannot operate by themselves, and the efficiency is low;
(3) only supporting the dependency relationship among sql type tasks, not supporting the dependency relationship among script type tasks and the dependency relationship among cross-workflow tasks, cannot support complex task dependency relationships, and is low in efficiency because cross-workflow tasks need to be checked one by one. Meanwhile, when problems occur, strong execution of cross-workflow is not supported, the workflow is clicked one by one to re-run the tasks, and the efficiency is low.

The method for issuing the offline data processing task provided by the embodiment of the invention comprises the following steps:
s101, according to the updating operation of the offline data processing tasks of the user, obtaining the latest codes of all the offline data processing tasks from a code review center Gerrit.
The plurality of offline data processing tasks form a workflow, and the workflow is formed by different tasks for establishing a dependency relationship. Each offline data processing task generates an operation record called as an offline data processing task instance after being executed, and records detailed information of the current offline data processing task operation, wherein the detailed information comprises operation starting time, end time, operation state, operation log, operation consumed resources and the like.
As a specific embodiment, after the developer develops the offline data processing task and submits the offline data processing task to the code review center Gerrit, the developer clicks an update task list button under the pivot offline data processing task management module, and the action triggers the code review center Gerrit to automatically pull the latest code data to the pivot system and display the latest code data to the developer.
S102, editing the latest codes, configuring each offline data processing task and setting the configured state of each offline data processing task as a to-be-issued state.
And S103, sending the offline data processing task in the state to be issued to a task scheduling center for issuing by using a scheduling engine.
Management operations such as offline, scheduling time setting, complement and the like of the offline data processing tasks are performed by clicking corresponding buttons in the system by data developers, and the task management service is cooperated with the scheduling engine to perform corresponding action processing, so that complete self-service of offline data processing task management is realized.

determining a source data table and a target data table associated with the offline data processing task according to the SQL statement;
and determining the offline data processing tasks with the dependency relationship with the offline data processing tasks according to the source data table and the target data table.
The dependency relationship comprises a strong dependency relationship and a weak dependency relationship, and one offline data processing task can establish different dependency relationships with a plurality of offline data processing tasks. If the offline data processing task A strongly depends on the offline data processing task B, the offline data processing task A is executed after the offline data processing task B is executed once and is normally finished; if offline data processing task a is weakly dependent on offline data processing task B, then offline data processing task a may be run as long as the running status of offline data processing task B is confirmed to be successful (offline data processing task B may have been executed once by being strongly dependent by other tasks).
Optionally, the issuing, by using the scheduling engine, the offline data processing task in the to-be-issued state to the task scheduling center includes:
determining a source data table and a target data table associated with the offline data processing task of the script type according to the source data table parameter and the target data table parameter in the execution parameters;
and determining the offline data processing tasks with the dependency relationship with the offline data processing tasks according to the source data table and the target data table.
Optionally, determining, according to the source data table and the target data table, an offline data processing task having a dependency relationship with the offline data processing task includes:
determining the type of the offline data processing task and the blood relationship between the offline data processing task and other offline data processing tasks according to the source data table and the target data table;
and determining the offline data processing tasks with the dependency relationship with the offline data processing tasks according to the types of the offline data processing tasks and the blood relationship between the offline data processing tasks and other offline data processing tasks.
